Description

display device

This application claims priority to and benefit from Korean Patent Application No. 10-2017-0088914, filed on July 13, 2017, which is incorporated herein by reference for all purposes as if set forth herein.

Technical field

Exemplary embodiments relate to a display device. More specifically, exemplary embodiments relate to a display device having improved display quality by reducing defects due to static electricity.

Background technique

Among display devices, organic light-emitting display devices have attracted attention as next-generation display devices due to their wide viewing angle, high contrast, and fast response time.

Generally, an organic light-emitting display device includes a thin film transistor (TFT) formed on a substrate and an organic light-emitting device that emits light by itself. Such organic light-emitting display devices are generally applied to small products such as mobile phones or large products such as televisions.

Such an organic light-emitting display device includes a display unit having an organic light-emitting device. The display unit includes an organic light emitting device and displays an image when the organic light emitting device emits light by itself. Different applications require display units to have different shapes that suit the specific application, rather than just the traditional rectangular shape.

A problem with a display device including a display unit having a non-rectangular shape is that parts of the display unit are susceptible to damage by static electricity due to structural differences between flat edges and non-flat edges. Static electricity can damage pixels and prevent the monitor from displaying high-quality images.

However, when an element or layer is referred to as being "directly on," "directly connected to" or "directly coupled to" another element or layer, there are no intervening elements or layers present. For the purpose of this disclosure, "at least one of X, Y, and Z" and "at least one selected from the group consisting of X, Y, and Z" may be construed as simply X, only Y, only Z, or any combination of two or more of X, Y, and Z, such as XYZ, XYY, YZ, and ZZ. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Although the terms "first," "second," etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. . These terms are used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the present disclosure.

For purposes of description, spatially relative terms such as “under,” “under,” “under,” “over,” and “on” may be used herein and are used thereby to describe the accompanying drawings. The relationship of one element or feature to other elements or features illustrated in the figures. In addition to the orientation depicted in the figures, spatially relative terms are intended to encompass different orientations of the device in use, operation, and/or manufacture. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below" may include both an above and below orientation. Furthermore, the device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

Thus, example embodiments disclosed herein should not be construed as limited to the shapes of particularly illustrated regions but are to include deviations in shapes that result, for example, from manufacturing. For example, an implanted region shown as a rectangle will typically have rounded or curved features and/or a gradient in implant concentration at its edges rather than a binary change from implanted to non-implanted region. Likewise, a buried region formed by an implant may result in some implantation in the area between the buried region and the surface through which the implant occurs. Therefore, the areas shown in the figures are schematic in nature and their shapes are not intended to illustrate the actual shape of the areas of the device and are not intended to be limiting.

Unless expressly so defined herein, terms (such as terms defined in general dictionaries) are to be construed to have a meaning consistent with their meaning in the context of the relevant art and are not to be construed in an ideal or overly formal sense.

1 is a plan view of a display device according to an embodiment. FIG. 2 is an enlarged plan view showing part A of the display device of FIG. 1 .

Referring to FIG. 1 , the display device according to the present embodiment includes a substrate 100 including a display area DA and a peripheral area PA disposed outside the display area DA. The peripheral area PA may surround the display area DA, and may be a non-emitting area where the display unit 200 is not disposed as described below.

The display area DA may include a main area DA3 disposed at the center of the substrate 100 and first and second protruding areas DA1 and DA2 extending from the main area DA3. In an exemplary embodiment, the main area DA3 may have, but is not limited to, a quadrangular shape. The first protruding area DA1 and the second protruding area DA2 may protrude from the display area DA toward the peripheral area PA in a first direction (eg, +y direction). That is, the first protruding area DA1 and the second protruding area DA2 may protrude in the same direction, and may be an area obtained when a portion of one side of the main area DA3 is extended. As shown in FIG. 2 , the first protruding area DA1 and the second protruding area DA2 may be spaced apart from each other in a second direction (eg, +x direction) intersecting the first direction (eg, +y direction).

The groove portion 100a may be formed in a portion of the base 100. The groove portion 100a may be disposed between the first and second protruding areas DA1 and DA2 of the display area DA. Although not shown, the display device according to the present embodiment may further include a camera module and/or a speaker module disposed in the groove portion 100a.

Referring to FIG. 2 , the display device according to the embodiment may include a display unit 200 disposed on the display area DA and first and second load matching parts LM1 and LM2 disposed on the peripheral area PA of the substrate 100 .

The display unit 200 may be disposed on the display area DA, and may include a first light emitter 210 disposed on a first protruding area DA1 of the display area DA, a second light emitter 210 disposed on a second protruding area DA2 of the display area DA. The emitter 220 and the third light emitter 230 are arranged on the main area DA3 of the display area DA. In this case, for convenience of explanation, the first light emitter 210 , the second light emitter 220 and the third light emitter 230 are conceptually distinguished according to positions, and may be actually integrated rather than separate light emitters. launcher. In the present embodiment, the first light emitter 210 and the second light emitter 220 may be disposed at one side of the third light emitter 230 which has a quadrilateral shape and is disposed on the main area DA3.

The first load matching part LM1 and the second load matching part LM2 may be disposed on the peripheral area PA of the substrate 100 . The first load matching portion LM1 may be disposed on a portion of the peripheral area PA adjacent to the first light emitter 210, and the second load matching portion LM2 may be disposed on a portion of the peripheral area PA adjacent to the second light emitter 220. superior. That is, the first load matching portion LM1 may be disposed on a portion of the peripheral area PA adjacent to the first light emitter 210 and may be electrically connected to the first light emitter 210 through the first wiring C1. In addition, the second load matching part LM2 may be disposed on a portion of the peripheral area PA adjacent to the second light emitter 220 and may be electrically connected to the second light emitter 220 through the second wiring C2.

In a conventional display device including the display unit 200 having a simple rectangular shape, the number of pixels of each line may be the same and the load applied to each line may be the same. However, in the display device according to the exemplary embodiment, as in the conventional display device, the third light emitter 230 disposed on the main area DA3 may have a rectangular shape, and therefore the load applied to each line is Similarly, on the contrary, the light emitter is not disposed between the first protruding area DA1 and the second protruding area DA2, therefore, the load applied to the first light emitter 210 and the second light emitter 220 may not be the same.

Therefore, in the display device according to the exemplary embodiment, the first load matching part LM1 and the second load matching part LM2 may be disposed in the peripheral area PA adjacent to the first light emitter 210 and the second light emitter 220 in part to be electrically connected to the first light emitter 210 and the second light emitter 220 and to be matched to a load applied to the line.

In an exemplary embodiment, the first load matching part LM1 and the second load matching part LM2 may be electrically connected to each other. The first load matching part LM1 and the second load matching part LM2 may be electrically connected to each other through the conductive film D. For example, in an exemplary embodiment, the conductive film D used to connect the first load matching part LM1 and the second load matching part LM2 may include, but is not limited to, the same material as the third conductive layer 515 described below. In this way, since the first load matching portion LM1 and the second load matching portion LM2 can be electrically connected, the equal potential area can be increased when static electricity is introduced, thereby preventing damage to the display area DA due to static electricity.

FIG. 3 is a plan view showing a part of the display device of FIG. 1 . FIG. 4 is a cross-sectional view taken along line A1 - A1 of the display device of FIG. 3 . 3 and 4 are enlarged views showing the structure of the first load matching part LM1 of FIG. 2 . The structure of the second load matching part LM2 of FIG. 2 is the same as that of the first load matching part LM1, so repeated explanation will not be given.

Referring to FIGS. 3 and 4 , the first load matching part 500 may include a first conductive layer 511 , a second conductive layer 513 disposed on the first conductive layer 511 , and a third conductive layer 515 disposed on the second conductive layer 513 . In this embodiment, the third conductive layer 515 may be formed in a first direction (eg, +y direction) or a second direction (eg, +x direction) intersecting the first direction (eg, +y direction). Patterned and extended. Referring to FIG. 3 , the first conductive layer 511 may extend in a first direction (eg, +y direction), and the second conductive layer 513 may extend in a second direction (eg, +y direction) intersecting the first direction (eg, +y direction). +x direction). That is, the first conductive layer 511 and the second conductive layer 513 may be arranged in a lattice form to be perpendicular to each other.

The third conductive layer 515 may be disposed on the second conductive layer 513 . As shown in FIG. 3 , like the first conductive layer 511 , the third conductive layer 515 may extend in a first direction (eg, +y direction) to overlap the first conductive layer 511 . In this embodiment, like the first conductive layer 511, the third conductive layer 515 may be patterned in one direction. Although the third conductive layer 515 is patterned in the first direction (eg, +y direction) in FIG. 3 , the present disclosure is not limited thereto. In other embodiments, it is Like layer 513, third conductive layer 515 may be patterned in a second direction (eg, +x direction).

Referring to FIG. 2 , as described above, the first load matching portion LM1 may be disposed on a portion of the peripheral area PA adjacent to the first light emitter 210 and may be electrically connected to the first light emitter 210 through the first wiring C1 , the second load matching part LM2 may be disposed on a portion of the peripheral area PA adjacent to the second light emitter 220, and may be electrically connected to the second light emitter 220 through the second wiring C2. In an exemplary embodiment, the first wiring C1 and the second wiring C2 may include, but are not limited to, the same material as the second conductive layer 513 .

In addition, as described above, the first load matching part LM1 and the second load matching part LM2 may be electrically connected to each other through the conductive film D. In embodiments, the conductive film D may include, but is not limited to, the same material as the third conductive layer 515 .

Referring to FIG. 4 , a first conductive layer 511 may be disposed on the substrate 100 and a second conductive layer 513 may be disposed on the first conductive layer 511 . Although the first conductive layer 511 may be directly disposed on the substrate 100 in FIG. 4 , an insulating layer or a buffer layer may also be disposed between the substrate 100 and the first conductive layer 511 . The first insulating film 120 may be disposed between the first conductive layer 511 and the second conductive layer 513 . The first insulating film 120 may be a gate insulating film as described below. The third conductive layer 515 may be disposed on the second conductive layer 513 . The second insulating film 130 may be disposed between the second conductive layer 513 and the third conductive layer 515 . The second insulating film 130 may be an interlayer insulating film as described below. Although not shown, the first conductive layer 511 and the third conductive layer 515 may be electrically connected to each other through the contact hole.

When the third conductive layer 515 is not divided by patterning, that is, when the third conductive layer 515 is formed as a common electrode, the amount of charge may increase proportionally as the area of the third conductive layer 515 increases. In this case, when static electricity is introduced into the third conductive layer 515 and then into the first light emitter 210 of the display unit 200 that is electrically connected to the third conductive layer 515, the static electricity may cause interference with the first light emission. Damage to the pixels of the display 210 and defects in the display area DA.

However, in the display device according to the embodiment, since the charge area of the third conductive layer 515 is reduced by using the patterned structure of the third conductive layer 515, the amount of charge can be reduced and a structure capable of reducing static electricity can be achieved.

FIG. 5 is a cross-sectional view showing a part of the display device of FIG. 1 .

Referring to FIG. 5 , a substrate 100 of a display device according to an exemplary embodiment includes a display area DA and a peripheral area PA disposed outside the display area DA. The substrate 100 may include any of a variety of flexible or bendable materials, such as, for example, polyethersulfone (PES), polyacrylate (PAR), polyetherimide (PEI), polyethylene naphthalate ester (PEN), polyethylene terephthalate (PET), polyphenylene sulfide (PPS), polyarylate, polyimide (PI), polycarbonate (PC) or cellulose acetate propionate (CAP) polymer resin.

As shown in FIG. 5 , a display device 300 and a thin film transistor (TFT) electrically connected to the display device 300 may be disposed on the display area DA of the substrate 100 . In FIG. 5 , an organic light-emitting device is disposed on the display area DA as the display device 300 . When the organic light emitting device is electrically connected to the TFT, it may mean that the pixel electrode 310 is electrically connected to the TFT. If necessary, a TFT (not shown) may also be disposed on the peripheral area PA outside the display area DA of the substrate 100. The TFT disposed on the peripheral area PA may be, for example, a part of a circuit unit for controlling electrical signals applied to the display area DA.

The TFT may include an active pattern 211, a gate electrode 213, a source electrode 215a, and a drain electrode 215b each including amorphous silicon, polycrystalline silicon, or an organic semiconductor material. In order to ensure insulation between the active pattern 211 and the gate electrode 213, the first insulating film 120 (hereinafter, referred to as a gate insulating film) including an inorganic material such as silicon oxide, silicon nitride, and/or silicon oxynitride may be Disposed between the active pattern 211 and the gate electrode 213. In addition, a second insulating film 130 (hereinafter, referred to as an interlayer insulating film) including an inorganic material such as silicon oxide, silicon nitride, and/or silicon oxynitride may be disposed on the gate electrode 213, the source electrode 215a, and the drain electrode. 215b may be disposed on the interlayer insulating film 130. Such an insulating film including an inorganic material can be formed by using chemical vapor deposition (CVD) or atomic layer deposition (ALD), which is applicable to the following embodiments and modifications thereof.

A buffer layer 110 including an inorganic material such as silicon oxide, silicon nitride, and/or silicon oxynitride may be disposed between the TFT and the substrate 100 . The buffer layer 110 may improve the flatness of the top surface of the substrate 100 or may prevent or minimize the penetration of impurities into the active pattern 211 of the TFT.

Planarization layer 140 may be disposed on the TFT. For example, when an organic light emitting device is disposed on a TFT as shown in FIG. 5, the planarization layer 140 may planarize a protective film covering the TFT. The planarization layer 140 may be formed of an organic material such as benzocyclobutene (BCB) or hexamethyldisiloxane (HMDSO). Although the planarization layer 140 has a single-layer structure in FIG. 5, various modifications may be made, for example, the planarization layer 140 may have a multi-layer structure.

An organic light emitting device including the pixel electrode 310, the counter electrode 330, and the intermediate layer 320 including the emission layer disposed between the pixel electrode 310 and the counter electrode 330 may be disposed on the planarization layer 140 within the display area DA of the substrate 100. As shown in FIG. 5 , the pixel electrode 310 may be electrically connected to the TFT by contacting any one of the source electrode 215 a and the drain electrode 215 b through an opening formed in the planarization layer 140 or the like.

The pixel defining film 150 may be disposed on the planarization layer 140. The pixel defining film 150 defines a pixel by having an opening corresponding to each sub-pixel (ie, an opening through which at least the central portion of the pixel electrode 310 is exposed). In addition, in FIG. 5 , the pixel defining film 150 prevents arcing or the like from occurring at the edge of the pixel electrode 310 by increasing the distance between the edge of the pixel electrode 310 and the counter electrode 330 disposed on the pixel electrode 310 . The pixel defining film 150 may be formed of an organic material such as polyimide or HMDSO.

The intermediate layer 320 of the organic light emitting device may include a low molecular weight material or a high molecular weight material. When the intermediate layer 320 includes a low molecular weight material, the intermediate layer 320 may have a single-layer structure or be stacked with a hole injection layer (HIL), a hole transport layer (HTL), an emission layer (EML), an electron transport layer (ETL), and A multilayer structure of an electron injection layer (EIL), and may include copper phthalocyanine (CuPc), N,N'-di(naphthyl-1-yl)-N,N'-diphenyl-benzidine (NPB) and any of various organic materials of tris-8-hydroxyquinoline aluminum (Alq3). The above-mentioned layers may be formed using vacuum deposition.

When the intermediate layer 320 includes a high molecular weight material, the intermediate layer 320 may have a structure including HTL and EML. In this case, HTL may include poly(3,4-ethylenedioxythiophene) (PEDOT) and EML may include polymeric materials such as poly-phenylenevinylene (PPV)-based materials or polyfluorene-based materials. Intermediate layer 320 may be formed using screen printing, inkjet printing, or laser induced thermal imaging (LITI).

However, the intermediate layer 320 is not limited thereto, and may have any of various other structures. The intermediate layer 320 may include a layer over the plurality of pixel electrodes 310 , or may include a plurality of layers patterned to correspond to the plurality of pixel electrodes 310 .

As shown in FIG. 5, the counter electrode 330 may be disposed on the display area DA to cover the display area DA. That is, the counter electrode 330 may be integrally formed with the plurality of organic light emitting devices, and may correspond to the plurality of pixel electrodes 310 .

Since the organic light-emitting device may be easily damaged by external moisture or oxygen, the encapsulation layer 400 may cover and protect the organic light-emitting device. The encapsulation layer 400 may cover the display area DA and may extend beyond the display area DA. As shown in FIG. 5 , the encapsulation layer 400 may include a first inorganic encapsulation layer 410 , an organic encapsulation layer 420 , and a second inorganic encapsulation layer 430 .

The first inorganic encapsulation layer 410 may cover the counter electrode 330 and may include silicon oxide, silicon nitride, and/or silicon oxynitride. If necessary, other layers such as a capping layer may be disposed between the first inorganic encapsulation layer 410 and the counter electrode 330. Since the first inorganic encapsulation layer 410 may be formed along the underlying structure, the top surface of the first inorganic encapsulation layer 410 may not be flat, as shown in FIG. 5 . Unlike the first inorganic encapsulation layer 410, the organic encapsulation layer 420 may cover the first inorganic encapsulation layer 410 and may have a substantially flat top surface. In detail, the top surface of the portion of the organic encapsulation layer 420 located on the display area DA may be substantially flat. The organic encapsulation layer 420 may include polyethylene terephthalate, polyethylene naphthalate, polycarbonate, polyimide, polyethylene sulfonate, polyoxymethylene, polyarylate, and At least one material selected from the group consisting of hexamethyldisiloxane. The second inorganic encapsulation layer 430 may cover the organic encapsulation layer 420 and may include silicon oxide, silicon nitride, and/or silicon oxynitride. The second inorganic encapsulation layer 430 may prevent the organic encapsulation layer 420 from being exposed to the outside by contacting the first inorganic encapsulation layer 410 at an edge outside the display area DA.

Since the encapsulation layer 400 may include the first inorganic encapsulation layer 410, the organic encapsulation layer 420 and the second inorganic encapsulation layer 430, even when a crack occurs in the encapsulation layer 400 through such a multi-layer structure, the crack will not occur in the first The inorganic encapsulation layer 410 and the organic encapsulation layer 420 or the organic encapsulation layer 420 and the second inorganic encapsulation layer 430 are connected. Therefore, the possibility of forming a path through which external moisture or oxygen penetrates into the display area DA can be prevented or minimized.

Although not shown, a polarizing plate (not shown) may be disposed on the encapsulation layer 400 using an optically clear adhesive (OCA). Polarizing plates reduce reflections of external light. For example, when the external light that has passed through the polarizing plate is reflected by the top surface of the counter electrode 330 and then passes through the polarizing plate again, the phase of the external light may change because the external light passes through the polarizing plate twice. As a result, the phase of the reflected light may be different from the phase of the external light introduced into the polarizing plate to generate destructive interference, thereby reducing reflection of the external light and improving visibility. As shown in FIG. 5 , the OCA and the polarizing plate may cover the opening of the planarization layer 140 . However, the display device according to exemplary embodiments may not include the polarizing plate, the polarizing plate may be omitted and other elements may be used. For example, reflection of external light can be reduced by omitting the polarizing plate and using a black matrix and color filter.

When the display area DA is the first protruding area DA1, the display unit 200 disposed on the display area DA may be the first light emitter 210. In this case, the first load matching portion LM1 (see FIG. 2 ) may be disposed on a portion of the peripheral area PA adjacent to the first light emitter 210 . In another exemplary embodiment, when the display area DA is the second protruding area DA2, the display unit 200 disposed on the display area DA may be the second light emitter 220. In this case, the second load matching portion LM2 (see FIG. 2 ) may be disposed on a portion of the peripheral area PA adjacent to the second light emitter 220 .

The second conductive layer 513 may be disposed on the first conductive layer 511 and may include the same material as the gate electrode 213 of the TFT. The gate insulating film 120 may extend to be disposed between the first conductive layer 511 and the second conductive layer 513 . The third conductive layer 515 may be disposed on the second conductive layer 513 and may include the same material as the source electrode 215a or the drain electrode 215b of the TFT. The interlayer insulating film 130 may extend to be disposed between the second conductive layer 153 and the third conductive layer 515 . An insulating layer may be disposed on the third conductive layer 515. The planarization layer 140 and the pixel defining film 150 may extend to be disposed on the third conductive layer 515 .

In addition, although the third conductive layer 515 is patterned into an island shape on the overlapping portion between the first conductive layer 511 and the second conductive layer 513 in this exemplary embodiment, the present disclosure is not limited thereto. The pattern shape of layer 515 may be any of a variety of other shapes.
